Objective To investigate the influence of service-learning model on medical graduates' ethical behavioral tendency. Methods A self-designed questionnaire was conducted among 302 medical students who have graduated in the last five years including the basic information, ethical behavioral tendency and participation of service-learning. The acquired data was analyzed and com-pared using chi-square test and unconditional logistic multiple regression. Results 68.2%(206/302) undergraduates participated in service-learning. Undergraduates participated in service-learning be-haved more ethical than those did not participated when facing the situation of patient' vomits (P=0.037). There were statistical differences in taking bribes from patients between those participated in service-learning and those did not (P=0.031). According to the results of unconditional logistic multiple regression analysis, whether participating in the service-learning is one of significant factors influenc-ing undergraduates' attitude towards bride-taking. Conclusions Medical students educated by service-learning model will exhibited more ethically accepted medical behaviors after becoming doctors. Ser-vice-learning model, a new medical education model, is worth promoting.

Objective To investigate the effect of allgeneic hematopoietic stem cell transplantation (allo-HSCT) for β-thalassemia major. Methods Twenty-four β-thalassemia major patients with median age of 4 years (range: 2~15 years), 18 boys and 6 girls, received allo-HSCT.They were classified into class Ⅱ-Ⅲ according to Pesaro thalassemia classification. Twenty-three transplantations were from sibling donor and 1 was from mother, either HLA-identical (n = 23) or HLA-mismatched (5/6) (n = 1). Fifteen patients received bone marrow transplantation (BMT) plus peripheral blood stem cell transplantation (PBSCT), and 9 were subjected to umbilical cord blood transplantation (UCBT). The conditioning regimen consisted of busalphan, cyclophosphamide,fludarabine, plus hydroxyurea before transplantation. Graft-versus-host disease (GVHD) prophylaxis included CsA, methotrexate, antilymphpcute globulin, and mycophenolate mofetil. The median follow-up period was 13 months (range: 3~69). Results Of 24 patients, there were 21 cases (87. 5 %) of disease-free survival, 1 (4. 2 %) transplantation-related death, and 2 cases (8. 3 %) of rejection. Three-year overall survival and disease-free survival rate was 91.7 % and 87. 5 %respectively. The cumulative incidence of grade Ⅱ -Ⅳ acute GVHD and chronic GVHD was 16. 7 %and 20. 3 %, particularly cumulative extensive chronic GVHD was 5. 0 %. Conclusion The sibling donor BMT plus PBSCT is an effective and safe way to treat β-thalassemia major. Cord blood is an important source of hematopoietic stem cells for HSCT. The protocol GVHD prophylaxis of CsA,MTX, ATG with a low-dose and short course of MMF can effectively reduce the incidence of severe acute GVHD, improve the outcome of thalassemia transplantation.

The competency-based medical education has formed a global trend, and puts forward a greater challenge for educational design of resident training. The traditional curriculum cannot meet the goal of competency-based education as the curriculum design is lack of theoretical support. Curriculum design is the core of training content, and serves as a significant contributing factor of training outcome. Based on the six-step approach curriculum design, the theory and practice are integrated to form a curriculum design based on theoretical guidance. Through feedback evaluation, the current curriculum design is continuously improved in order to achieve a higher competency-based training quality. With the 5-year experiences and practice, preliminary reform demonstrates effectiveness. The current study hopes to share the teaching reform experiences of residency training base and provide references for colleagues of medical education.

Objective:To investigate mentor-mentee dual evaluation of the current status of mentor competency of clinical and translational research mentors, and provide the basis for mentor training focused on the mentor competences.Methods:A total of 121 clinical and translational research mentors and 170 mentees from Peking Union Medical College Hospital were enrolled. The Chinese version of the Mentor Competency Assessment (MCA) questionnaire was used to evaluate the mentor competency, including maintaining effective communication, aligning expectations, assessing understanding, fostering independence, addressing diversity, promoting professional development total 6 parts with 26 sub-items. The Likert scale was used to quantitatively evaluate the clinical and translational research mentor competency by mentor-mentee dual evaluations. And the composition and training needs of clinical and translational research mentors were investigated. SPSS 25.0 was used for t-test. Results:Seventy percent (119/170) of mentees considered the mentor guidance was very helpful, and 78.5% (95/121) of the mentors considered it necessary to carry out the mentor training. The mentee evaluation of mentor competency was significantly higher than that of mentor self-evaluation [total score (162.35±23.59) vs. (154.80±19.81), P < 0.01]. And the excellent rate of 26 sub-items by mentees and mentors were 100.0%(170/170) and 46.3%(56/121) respectively. The mentors and mentees shared the agreement of the strengths on trust-based relationship and encouraging mentees, and weaknesses on taking into account the possible prejudices in mentor-mentee relationship. Conclusion:The clinical and translational research mentors have already had good competences, but mentor training is still highly warranted. It's expected that to carry out targeted mentor training and assessment according to the mentor's competences will help to improve the construction of the medical talents training system.

Objective:To investigate the clinical utility of 68Ga-labeled fibroblast activation protein inhibitor (FAPI) PET/CT in the detection of primary and metastatic gastric signet-ring cell carcinoma (GSRCC) and compared the results with those of 18F-FDG PET/CT. Methods:A total of 21 patients (10 males, 11 females, average age 52 years) with primary and metastatic GSRCC who underwent 68Ga-FAPI and 18F-FDG PET/CT at the First Affiliated Hospital of Xiamen University from June 2020 to May 2022 were retrospectively analyzed. Pathological results of surgery and (or) biopsy were used as the " gold standard" for final diagnosis. In cases whose surgery or tissue biopsies were not available, clinical and radiographic follow-up results were used as the reference standards. Wilcoxon signed-rank test was used to compare the SUV max of 18F-FDG and 68Ga-FAPI. McNemar χ2 test was used to compare the detection rate between 18F-FDG and 68Ga-FAPI PET/CT. Results:68Ga-FAPI PET/CT showed higher SUV max than 18F-FDG in primary tumors (5.3(2.4, 15.7) vs 2.4(1.8, 2.5); z=2.31, P=0.021), local recurrences (7.8(6.0, 8.9) vs 2.4(1.9, 3.4); z=2.20, P=0.028), lymph nodes metastases (7.7(4.5, 12.2) vs 2.4(1.9, 3.6); z=6.01, P<0.001) and bone/visceral metastases (6.7(5.3, 11.1) vs 2.4(2.0, 3.4); z=11.36, P<0.001). Regarding diagnostic accuracy, 68Ga-FAPI PET/CT showed higher sensitivities than 18F-FDG for primary tumors (7/9 vs 2/9; χ2=3.20, P=0.063) and local recurrences (7/7 vs 2/7; χ2=3.20, P=0.063). It also demonstrated higher lesion detection rates than 18F-FDG for suspicious lymph node metastases (86%(65/76) vs 32%(24/76); χ2=31.37, P<0.001) and bone/visceral metastases (99%(184/185) vs 39%(73/185); χ2=107.08, P<0.001). Conclusions:68Ga-FAPI PET/CT showed higher tumor uptake and lesion detection rate than 18F-FDG in the primary and metastatic GSRCC. 68Ga-FAPI PET/CT demonstrates good diagnostic performance for tumor detection, staging, and restaging of GSRCC, which is helpful to further guide clinical treatment strategy.
